A more thorough explanation:

The Court of the Lord High Admiral was a court in England that dealt with legal matters related to shipping, collisions, and salvage cases. It was established in the 14th century and initially focused on prize and piracy cases. Over time, its jurisdiction expanded to include criminal matters and other areas of law not directly related to maritime issues.

In 1873-1875, the Court was merged into the High Court as part of the Probate, Divorce, and Admiralty Division. In 1970, a new Admiralty Court was established as part of the Queen's Bench Division of the High Court, which is regulated by the Supreme Court Act of 1981.

For example, if a ship collided with another ship and caused damage, the Court of the Lord High Admiral would have jurisdiction over the case and would determine who was at fault and what damages should be paid. Similarly, if a ship was salvaged after being stranded, the Court would determine the appropriate compensation for the salvors.
